BIB OR COCK.

SPECIFICATION forming part of Letters Patent No. 433,999, dated August 12, 1890.

, Application filed January 24, 1890. Serial No. 338,019. (No model.)

To all whom it may concern: Be it known that I, WILLIAM LOOKE RIAN- HARD, a citizen of the United States, residing at Ansonia,in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Bibs or Cocks; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as will enable .others skilled in the art to'which it appertains to make and use the same.

My invention relates to special improvements in the details of construction of bibs or cocks, and has for its object to simplify, cheapen, and to generally improve the details of construction, and more especially to pro Vide a novel stop formed integral with the plug which shall avoid the serious danger of breakage of the stops, and consequently the escape of gas, as where pin-stops are used in gas-fixtures.

\Vit-h these ends in view I have devised the simple and novel construction, of which the following description, in connection with the accompanying drawings, is a specification, numbers being used to denote the several parts.

Figure l is a side elevation of the device complete; Fig. 2, a plan View of the body, the plug being removed; Fig. 3, an inverted plan view of the plug detached, and Fig. 4 a side elevation of the plug detached.

It will of course be apparent that my invention is applicable to the various styles of bibs and cooks in general use. As it is espe cially adapted to gas-cocks, however, I have illustrated its use as applied to a gascock, and have not deemed it necessary to illustrate other uses of the principle involved.

1 denotes the body of the cook, which may be of the ordinary or any preferred construction, and which is provided with the usual tapered opening 2 through it. At the upper edge of this tapered opening is a flat surface 3, which extends almost entirely around the opening. 4 is a flange which partially surrounds this opening and rises above surface 3. In cocks and bibs of this class, as ordinarily constructed, this flange is made about as wide as the flat surface, the inner side of the flange being 'in line with the wall of the opening through the body, the flange BXIQHCI- in g approximately half-way around the opening. In my improved cock, however, this flange at one end is made the full width of surface 3, but tapers continuously to the other end, the taper being all upon the inner side, so that surface 3 extends almost entirely around the opening. For convenience in illustration I designate the shoulder at the thick end of the flange as 4." and the shoulder at the reduced end of the flange as 4t In order to make the construction perfectly clear, suppose that the flat surface begins at shoulder 4t, the width of this surface being the same until shoulder 4 is reached. From this point, however, the width of the surface lessens until it vanishes entirely before shoulder 4 is reached. It will of course be understood without illustration that the body is provided with the usual longitudinal opening through it.

5 denotes a plug, which is tapered to correspond with the taper of opening 2, and is pro vided with a transverse opening 6, which is adapted to register with the longitudinal opening (not shown) in the body.

7 is the usual finger-piece for convenience in operating the plug. The plug is preferably, although not necessarily, provided with a circular flange 8, which rests upon the top of flange 4 on the body. Under this flange, however, and forming an essential portion of my invention, is a curved tapering flange 9, the base of which rests in use upon surface 3. This flange rises from the tapered surface of the plug and gradually increases in thickness until a shoulder 10 is reached, which in use is adapted to engage the shoulder 49 at the reduced end of flange 4, thereby forming a stop to limit the rotation of the plug in one direction. This flange terminates at short distance from shoulder 10 in an abrupt shoulder 11, which rises from the tapered surface of the plug and is adapted in use to engage the shoulder l at the thick end of flange 4. It will thus be seen that by means of the tapered flanges at and 9 and the shoulders I provide stops to limit the rotation of the plug in both directions, forming a perfect safeguard against the escape of gas and avoiding the use of the double-pin stop which has been found so objectionable in practice, it being impossible,in fact, with my present construc- ICO tion, for any breakage to occur, or that there should be any escape of gas so long as the most ordinary care is observed in turning. it on and off. The plug passes through the body in the usual man n er, the lower end thereof being engaged by a washer 12, one side of the Washer and the end of the plug being flattened in the usual way, so that the washer will turn with the plug.

- other, both ends terminating in a shoulder,

and a plug having a correspondinglytapered flange adapted to pass within the flange on the body, the incline upon the plug rising from the surface thereof and terminating in a shoulder adapted to engage the reduced end of the flange on the body, and just be yond said shoulde r being provided with another shoulder rising abruptly from the surface of the plug, which is adapted to engage the shoulder at the thickest end of the flange on the body.

2. The combination, with the body of a bib or cook having upon the upper edge of the opening a flange made thickest at one end and tapering toward the other, so that a flat surface is left between the reduced end of the flange and the opening, of a plug having a eorrespondingly-tapered flange adapted to pass within the flange on the body and to rest on the top of the surface thereof, the flange on the plug being provided with astop adapted to engage the reduced end of the flange 011 the body, and just beyond said stop another stop adapted to engage the shoulder at the thick end of the flange on the body when turned in the opposite direction.

In testimony whereof I aflix m y signature in presence of two witnesses.

WILLIAM LOCKE RIANHARD.
